Hiperface encoder
Hiperface is a mixture of incremental encoder and absolute encoder and combines the advantages of
both encoder types. The absolute value is initially only formed when the device is switched on and is
communicated by the RS485 specification bus parameter interface to the external counter in the
controller, which then continues counting incrementally from this absolute value using the analog
sine/cosine signal. During operation the counted position is continuously compared with the measured
absolute position of the encoder.
Hiperface encoders are suitable for positioning in combination with servo mode.
The requirements for the analog signal are shown in the following table. It must be noted that the
tolerances in the voltages affect the precision of the determined position.
The supply voltage for the encoder is 7-12V. An external source or the internal 12V voltage can be
used as the voltage supply.
